Description
Technical Field
The invention relates to the technical field of elevator safety protection, in particular to a foundation pit-free elevator safety protection device.
Background
The elevator is a vertical elevator powered by an electric motor and is provided with a box-shaped nacelle for use in multi-story buildings for taking persons or carrying goods. There are also steps, where the tread is mounted on a track for continuous running, commonly known as an escalator or a travelator. A stationary lifting device serving a prescribed floor. The vertical lift elevator has a car running between at least two rows of rigid guide rails that are vertical or have an incline angle of less than 15. The size and the structural form of the lift car are convenient for passengers to get in and out or load and unload cargoes. Traditionally, elevators have been known as vertical transportation means within a building, regardless of the manner in which they are driven. The speed can be divided into a low-speed elevator (below 1 m/s), a quick elevator (1-2 m/s) and a high-speed elevator (above 2 m/s). Hydraulic elevators began to appear in the middle of the 19 th century and have been used in low-rise buildings to date. In 1852, e.g. ottes in the united states developed a rope lift safety elevator. In the 80 s, the driving device is further improved, such as a motor drives a winding drum through worm transmission, a counterweight is adopted, and the like. At the end of the 19 th century, friction wheel transmission is adopted, so that the lifting height of the elevator is greatly increased.
Because there is not pit in the bottom of the elevator without foundation pit, in terms of the present, the hydraulic pressure, the traction is relatively suitable for the high-rise, the screw elevator is relatively suitable for the low-rise or compound building villa, there is not too much requirement on the foundation pit, the screw elevator adopts the motor as the power source, the motor is connected with nut through the belt, and the nut insection is meshed with the nut insection with yin and yang between the nut insection, when the motor works, the driving nut moves on the screw, thus drive the car to do up-down movement. The safety is higher because it is that there is the thing to prop under it always, even lose electric power, the free fall descends, and the screw rod is also driven the motor and is done great burden work, and the decline speed is slower, but a long screw thread can skid in time, if the screw thread skids can lead to the elevator to drop down rapidly, leads to the passenger to be injured or frightened, so the safety protection equipment of a set of accident prevention measures of needs to be designed.
